2 Assembly/Disassembly
To remove the control module from the power base, loosen the captive screw underneath the thermostat and pull the two components apart as shown. To install the control module onto the power base, reverse the above procedure.
NOTE: Always keep the thermostat's vents clean and unobstructed.
3 Configuration
Some thermostat configurations can be modified via the switches on the back of the control module.
Default (factory) settings are inside the gray cells.
Configuration Switches
| # | Configurations | UP | DN |
|---|---|---|---|
| SW1 | Temperature format a | °F | °C |
| SW2 | Early Start b | Disable | Enable |
| SW3 | Time format | 12-hour | 24-hour |
a. If you change the temperature display format, the preset buttons ([Comfort Preset], [Economy Preset], and [Vacation Preset]) will return to their default settings.
b. Early Start can be used in Automatic mode only. When this function is enabled, the thermostat calculates the optimal time to start heating in order to obtain the desired temperature by the set time. The thermostat re-assesses the start time daily based on the previous day's performance.
4 Power-up
Upon power-up, the thermostat is in manual mode ([Manual Mode]) and displays the actual temperature.
- Press the Hour and Min buttons to set the time.
- Press the Day button to set the day.

| 4 | Sleep | [Economy Preset] |
The [Comfort Preset] temperature is used in periods 1 and 3 and the [Economy Preset] temperature is used in periods 2 and 4. For example, when the period changes from 1 to 2, the setpoint automatically changes from Comfort setting ([Comfort Preset]) to Economy setting ([Economy Preset]).
You can have a different program for each day of the week; i.e., each period can start at different times for each day of the week. The thermostat has been programmed with the following schedule.
